Running Benchmarks

To run the benchmark suite locally:

# Start MinIO for S3-compatible storage
make bench-minio

# Run all benchmarks
make bench-all

# Or run individual benchmarks
make bench-compare    # Memory/CPU comparison
make bench-multidb    # Multi-database performance
make bench-realworld  # Sync latency, restore, throughput

# Stop MinIO when done
make bench-minio-stop

JSON Output

All benchmarks support JSON output for CI integration:

python bench/compare.py --use-minio --json > results.json
